On June 3, 2015, the Canada Border Services Agency (CBSA) made final determinations of dumping and subsidy in respect of certain photovoltaic modules and laminates originating in or exported from China. The Canadian International Trade Tribunal found the threat of injury to the domestic industry on July 3, 2015, thus resulting in the orders against these imports.

The case began when CBSA announced on December 5, 2014 that it was initiating investigations into the alleged injurious dumping and subsidizing of certain photovoltaic modules and laminates originating in or exported from China. The investigations follow a complaint filed by four Canadian firms all located in Ontario, namely Eclipsall Energy Corporation, Heliene Inc., Silfab Ontario Inc., and Solgate Inc.

The Canadian International Trade Tribunal announced on February 3, 2015 that it had reached an affirmative determination in its preliminary inquiry to determine whether the imports are harming Canadian producers. On March 5, 2015, the CBSA made preliminary determinations of dumping and subsidizing with respect to these products.
